Bengals sign another CFA

The Bengals free-agent rookie class grew to 15 Friday when they announced the signing of Notre Dame guard Trevor Robinson. Robinson, a 6-5, 310-pounder from Elkhorn, Neb., played 48 games for the Irish as a four-year starter. An anchor of an offensive line that accounted for more than 20 rushing touchdowns while averaging nearly 180 yards per game on the ground in 2011, Robinson also figures to see some practice time at center.
